Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a system and method for a wireless terminal to securely access an information intranet. Background technique [0002] With the construction of smart grid and SG-ERP (State Grid Resource Plan), higher requirements are put forward for the confidentiality, integrity and availability of information security of State Grid Corporation. At present, various application systems have gradually adopted mobile operation terminal access methods to exchange data through wireless access technologies such as GPRS / CDMA / 3G and information intranets. In this situation, how to ensure that all kinds of scattered access objects are safely and credibly connected to the power information network, while ensuring that confidential data will not be leaked, and how to monitor and audit access objects and operations has become an issue. Become the basic power to support the current ...
